Fig. 7. Elk River Sediment Loads
A map layer (shapefile) of sediment loads in the Elk River watershed by study subbasin. The watershed subbasin boundaries were created in 2005-2007 and were loosely matched with CalWater’s planning watersheds for reference. The sediment loads were derived from the Upper Elk River: Technical Analysis for Sediment report (pages 59-60, Table 8) published by the North Coast Regional Water Quality Control Board in October 2015. The dataset includes PWS (Public Water System) Name and Average Sediment Load (in cubic yards per square mile per year).
